This invention relates to a conveyor belt 9nd to nieans for guiding saidbelt, the application being a' division of our prior application, SerialNo. 610,799, filed January 5, 1923, on a vcoating machine.

It is one object of our invention to provvide a conveyer belt of specialconstruction and having 'strongly reinforced or thickened edges. to lltis another object of ourI invention/to provide guide pulleys, rolls, orother devices for such a belt, so constructed that they will co-operatewith the reinforced edges ofthe belt and will cause the belt to travelin a ,w straight path. l

Uur invention further relates to varrangements and combinations 'ofparts which will be hereinafter described and more particu; larlypointed out in the appendedv claims.

A preferred form 'of the invention 1s shown in the drawings, in whichFig. 1 is a side elevation of a portion of our improved belt and aguiding drum o pulley therefor;l p et Fi 2 is a sectional elevation,taken along the line 2--2 in Fig. l; and l Fi 3 is a sectionalelevation, taken along the line 3 3 in Fig.`1.

Referring to the drawings, I have shown 3o a portion of n iy improvedconveyer belt coui-y prising a main or body portion formed of a suitableexible sheet material such as a duck or canvas of substantial thickness.

At one or both edges,the belt is thickened, preferably Vby a reinforcingband or strip 11 forming an, abrii t shoulder and secured to one face ofthe elt, in osition for engagement with the sucpportin drums, pulleys orother guiding evices t erefor.4 y

proved conveyor belt as running over a drum 12 having a cylindricalportion 13 andhaving a depressed portion or recess 14 formed at one orboth ends of said portion-,13.

Both the 'cylindrical portion 13 and the lrecessed layer of felt orfabric 15, as indicated 1n Fig. 3, if Aso desired. This fabric 15acts.to cushion the conveyer belt, thus reducing 'thewean and also increasesthe friction for ''drivingtliebelt. n

In the drawings, we have'shown our iinl'i4 portion 14 may. be coveredwith a f this application aieiioetber As the belt 1,0 runs over the thereinforced edge or -ed es of the belt are receiyed in the recesseportions 14 of the drm'and thebelt -is thusv forced to follow a straightpath and is prevented from working out of alignment toward either endAof i In Figs. l and 2, AWe have indicated the construction of anadditional supporting roll 16, .one or more which it is desirable to usewhere the conveyer is ofsubstantial length,

Each of these' rolls l16 is reduced in diamethe inner edges of the,reinforcing strips 11' and assist the drums 12 in guiding thebelt in astraight path.

To prevent upward displacement, ofthe belt as it passes overtheguide-rolls 16, We preferably provide idle .rolls 20 mounted on studs 21 and positioned so closely adjacent ,the rolls 16 that the belt cannotlift away Afom the rolls suciently to carr the reinforcing strip 1 5above the shoul er 18.

`While Vthis vconveyor belt has been found ing strips 15 not onlyenables us to'guide our belt in a straight path but also increases thestrength and durability of the belt, as `the edge ortions, whichcommonly Wear most rapidly, are strongly reinforced and arev Welladapted to sustain the increased wear. Itv will be understood that thethickened edge` portions are not necessarily l. formed by attaching astrip of separatema- Having thus described our invention andthe-advantages thereof, we do -not wish to be limited to the detailsherein disclosed otherwise than as set forth in fthe claims, but whatweclaim is v 1. A conve er beglt formed of exible sheet material havingalong its edge a reinforcin guide stri of substantial 'thickness appliedto that si elof thebelt 'whichengages the su porting' and guidingdevices therefor,

fan

citic purpose. The addition of the reinforc' aguidin'g device thereforhaving@ re- 'A cessed end portion to receive said reinforcing strip andhaving a shoulder by which sai strip is aligned.

2. A conveyer belt having thickened edges, a rotating guiding devicehaving. recessed portions to receive said thickened edges, and holdingdevices adjacent said recessed rolls7 said holding device havingrecessed portions to engage said thickened edges and eifective lo retainthe thickened edges of said roll belt iu said recess. f

A conveyer belt having thickened edges, a rotating guiding device havingrecessed portions to receive said thickened edges, and holding rollsadjacent said recessed portions and spaced from the normal surface ofsaid guiding device by less than the thickness of said belt edges, saidholding rolls having recessed ends to engage said thickened edgeswhereby to retain the thickened edges of said belt in said recessedportions.

idle roll mounted above said belt adjacent said guiding device effectiveto retain said belt in engagement with said guiding device.

5. A conveyer belt having thickened edges, a rotated guiding devicehaving recessed portions to receive said thickened edges, and holdingdevices adjacent said recessed guiding device mounted transversely ofthe un# derside of said belt and effective to retain the thickened edgesof lsaid belt in said recess. ln testimony whereof we have hereuntoatixed our signatures,
